Guido Strazza was born in Santa Flora (Grosseto) in 1922.
In the Forties he gets in touch with Marinetti and he starts to take part in the exhibitions of Aeropittura.
In 1942 he is present at the Venice Biennale.
After graduating in Engineering, in 1949 he is in Peru where he is one of the organizers of "Agrupacion Espacio" a group of artists and architects who are involved in the rebuilding of Callao, a town devastated by an earthquake.
In this period he leaves his job of engineer in order to be a painter. In fact in 1953 he makes his first etchings in Rio, with the etcher Faiga Ostrower.
In 1954 he comes back to Italy and settles in Venice, where he comes in contact with Tancredi, Vedova, Bacci and the artists who are connected with the Cavallino Gallery.
In 1957 he moves to Milan where he gets in touch with Fontana and Capogrossi. He also works with Sottsass in order to plan the Venini pavilion for the X Triennale.
Through the two cycles of Balzi Rossi (1958) and Paesaggio Olandese (1960) Strazza reveals is interest for the metamorphosis of the shapes.
In 1964 he moves to Rome and he attends the National Institute of copper-engraving, directed by Maurizio Calvesi. He begins the exploration of copper-engraving, by considering the relationship between sign and colour.
In 1965 he paints the Way of the Cross for the Ponte Lambro church. In 1968 he exhibits at the XX Venice Biennale.
In 1971 the artist gets the professorship in etching, from the New Academy in l'Aquila.
In the period 1974-76 Strazza works again with the National Institute of copper-engraving of Rome, and he directs a group of research to study the sign, the results of this inquiry come together in the book Il gesto e il segno (1979).
Strazza changes his approch to art by passing from an analalytic rigour to an interest for the creative act. This act represents for him a place and a moment in which there is a union of project and fortuitousness, that means a union between order and the negation of order.
Strazza realizes this purpose through an artistc path which begings with his cycle of paintings and etchings Trama quadrangolare(1979), it continues with the cycle Segni di Roma (1980) where he makes works in black and white, and it arrives to an evident interaction between geometry and colour with the cycle Cosmati, shown at the Galleria Giulia in Rome, in 1982, and at the Biennale of Venice in 1983.
In 1985 he is elected director of the Rome Academy of Fine Arts. In 1988 the Academy of the Lincei awards the Feltrinelli Prize for Graphic to the artist.
In the Nineties he participates to several collective exhibitions such as Il segno esemplare. Premesse a nuove tecnologie dell'arte ( Rome,1993) and Matera e i suoi dintorni psicologici (Milano, 1996).
Now he lives in Rome and he his works are still shown in different Italian cities.
